Step 2: Sizing Your Blocks, Batting and Back
For my project, I decided to make a baby sized quilt, approximately 36” x 45”. My design used 4 blocks across, and 5 rows, all of which were 9” finished size. I will use this as an example, but you can certainly use different sizes/patterns to work within your project.
Once I pieced my top blocks, I trimmed them to be 9” PLUS seam allowance. I would really recommend using at least half of an inch around each side of each block. (I only used ¼”, and drove me totally bonkers and didn’t work out as well as I would have liked.)
When you have your top blocks trimmed, you will need to trim backing squares to be the exact same size as the top.
Once you have your top and backing cut, cut your batting to size. This part is a bit different… you want your batting to not have any seam allowance at all. If batting is running into your seam, you’ll have far too much bulk in your seams. For example, in my quilt, my batting squares were each 9” even.
